COMBINED HINGE-GAGE AND SQUARE.

SPECIFICATION forming part of Letters Patent No. 531,114, dated December 18, 1894.

Application filed October 9,1893. Serial No.487,566. (N model.) I

provide a gage, adapted for use either as a" hinge-gage or mortise gage, which shall be I light, convenient and efficient for use; and

also of such form and construction that it can be used as a try-square for making the ends of mortisesand hinge recesses.-

Another object is to provide a hinge-gage having facilities for adjustment whereby the.

relative distances for the door markings and rabbet markings for the hinge can be varied in relation to each other, as hereinafter explained. 2 5 These objects I attain by a gage or instrument embodying the peculiar construction shown in the drawings, wherein Figure 1 is a top view; Fig. 2, a front end view; Fig. 3, a side view; Fig. 4, a transverse 0 section at line X X on Fig. 3. Fig. 5 is a bottom View; Fig. 6, a rear end view. Fig. 7 is a sectional View showing the point-carrying rod, and the adjustable gage point separate from the frame, and Fig. 8 is an end view 0t the rod and adjustable point.

The instrument or gage, constructed in accordance with my invention, consists of a light rectangular frame or body A, flat upon its under face a and having, upon its upper I side a raised or arched central portion A extending longitudinally from end to end and embracing an interior chamber 0, within which there are arranged two longitudinal, adjustable, point-carrying rods D and E; one of which rods, D, has both the hinge-gaging pointsb and d connected therewith, as more fully hereinafter explained; while the other rod, E, carries the depth-gaging point e. The ends of the rods are best slitted as at s to 0 form a spring-grip for holding the points (1 and e. 1 p The body or frameA is shaped with straight rod from the inner end of the slot.

parallel side-edges 3, 3, that are square or at right angles with its ends F and G; the body and ends being of equal Width without lateral 5 5 projections. The body or frame is best made of sheet metal, the portion A struck up to form the arch and the parts rigidly attached together by rivets 4, as indicated. The end G of the body-frame has an upwardly directed 6o flange 6; and the end F has an end plate that forms an upwardflange 7 and a downwardly extendinglip 8, both the inner and outer surfaces of which are square with the bottom surface a and sides 3, 3, of the body. The end plate is provided with two openings through which the rods D and E are respectively arranged; said openings fitting to and serving as guides for the same. The inner ends of the rods are guided within the chamber 0. Longitudinal slots I'and J are out through the arched portion A into the chamber 0,

.and set screws H and Kext'end through the slots and screw into the respective rodsD and E for clamping the same at positions of adjustment. Bearing rings or segmental plates m m are preferably arranged on the rods beneath the screws to afiord a broader bearing than the surface of the rod, along the slots. These rings may in some instances be omitted.

A longitudinal slot L is formed in the bottom face of the frame, through which the point 1) projects. The point I) is best made in angular form and secured to the rod D in the manner indicated in Fig. 7; wherein the rod D is transversely slotted at its end 9, and has a holelO drilled longitudinally into the The shank end I) of the marker is inserted in the hole 10 and secured by a set screw 12 fitted in the under side of the rod, while the point end of the marker projects downward from between the sides of the slot 9; the point being thereby prevented from turning laterally. By loosening the screw 12 the point can be adjusted longitudinally of the rod to vary the distance between the two points I) and d. This adjustment renders the gage capable of being set to give a-greater or less clearance between the door and its rabbet shoulder, a feature which, so far as I am aware, has not heretofore been employed in hinge gages. The head of the set screw 12 runs in the slot L of the frame without projectingbeyond the surface, and is accessible from the bottom of the gage.

In the operation, adjustment of the rod D carries the gage-point 1) toward or from the end G and simultaneously carries the point (1 toward or from the face F: The point 12 serves for marking the line for the width of the hinge-plate recess on the door-jamb, with the end G run against the rabbet shoulder; and the point 01 serves for marking the corresponding line upon the door, with the face plate F run against the side of the door. The transverse lines for the ends of the hinge recess can be squared up; those for the jamb, by placing the end G against the shoulder of the rabbet and marking along the edge 3; and those upon the door, by placing the lip 8 against the angle of the door and in like manner marking along the edge 3, the instrument thus forming a very convenient square for marking transverse lines, in connection with the gages for marking the longitudinal lines for the hinge. The point e can be used for marking the depth or thickness of the hingeplate; or the instrument can be used for general gaging purposes when desired.

It will be understood that I do not claim, broadly, the feature of providing a gage with two marking points, which points can both be set simultaneously by a single adjustment, for indicating the position of the hinge on both the door and the door-jamb, as I am aware that such feature is well known in different forms of gages.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A hinge-gage provided with markers for respectively laying off the width of the hinge 011 both the door and jamb, and having a body or frame with a fiat under face, and provided with thin laterally extending plates or flanges, rectangular in shape with its side edges at right angles to its ends and provided at one end with an upward rectangular face, and at its other end with a downward rectangular face, as set forth; whereby the gage is adapted for use as a square upon the door-jamb or door, for laying off transverse lines, as the ends of the hinge-recess.

2. In a hinge'gage having a pair of marking points respectively adapted for gaging the width for the hinge upon the door and door-jarnb,both controlled by a single adj ustment; the combination with one of said marking points, of means for the slight independent adjustment of the same toward or from the other point for indicating greater or less amount of clearance for the door, as set forth.

3. The body or frame having the flat parallel side flanges, the square ends forming right angles therewith and raised central portion with the internal chamber and two Ion-- gitudinal slots thereinto; in combination with the two cylindrical point carrying rods adjustably arranged Within said frame and projecting from one end thereof, the marking points fixed in said rods, and the rod-clamping screws, as shown and described.

4. In a hinge-gage the body or frame formed of sheet metal and consisting of the rectangular bottom-plate having the upturned square end 6, the upper arched portion having longitudinal slots therein and its side plates connected to said bottom plate by rivets 4E, and the rigidly attached end-plate having the downwardly extending squaringlip S and openings for guiding the point-carrier rods, in combination with the point-carrier rods, the marking points fixed therein, and the set-screws for retaining said rods, as set forth.

\Vitness my hand this 6th day of October, A. D. 1893.
